janet cull Posted February 19, 2021 Share Posted February 19, 2021 Hello, I haven't been on here for so long. Everything looks different. I guess I need to learn my way around again. I changed the bulb in my Durst M605 enlarger tonight and something is wrong. When I open my enlarger lens all the way it isn't as bright as before, and it seems to heat up quickly. Ooh, I hope the enlarger isn't about to konk out! Which forum should I be asking this question in please? THanks. Janet Link to comment Share on other sites More sharing options...

Janet I had a Durst M 600 many years ago, and as I remember the position of the bulb on that enlarger was a friction fit and the socket could move up and down. If it wasn't centered on the condensor then the illumination was lower and inconsistent. Check the position of the bulb again and maybe you will find the problem.

janet cull Posted February 19, 2021 Author Share Posted February 19, 2021 Thank you. I had one more new bumb and tried that one. It's working perfectly! I don't know if I positioned the other one wrong or not but I took it out and put in again - at least 3 times snd the illumination was just wrong. I'm so relieved!! Thank you for your quick reply. Makes me want to get back on this forum more often. It's been a long while! Link to comment Share on other sites More sharing options...
Gary Naka Posted February 19, 2021 Share Posted February 19, 2021 @janet cull What bulb did you get? According to the manual, the M605 uses a 150w bulb (PH212) On my m600, I found 150w to be toooo bright, and went down to 75w (PH211), which was still marginally too bright. I would have preferred a 30w bulb. @AJG same as the 605 Link to comment Share on other sites More sharing options...

janet cull Posted February 19, 2021 Author Share Posted February 19, 2021 My and larger says not to use anything higher than 100W. My bulbs are 62V 85W. I'm so happy to have found it was just a bad bulb! Link to comment Share on other sites More sharing options...

I'm so happy to have found it was just a bad bulb! 62V ??? Where are you located? I thought all AC was either 110 or 220volts. Here is the page out of the M605 manual. Does the front of your enlarger look like the green circle in the pic above? Or the blue circle below? The M605 with the color head uses a dichroic bulb 12V and I think 100w. I suspect you have the color head on your enlarger. dupe pic below Link to comment Share on other sites More sharing options...
rodeo_joe1 Posted February 19, 2021 Share Posted February 19, 2021 62v seems extremely weird. Those Philips enlarger bulbs are getting quite hard to find.... and expensive. Assuming the 62 volt thing is wrong, you might want to try a 'daylight' type LED household bulb. Many of these have a plain opal cap (no lettering stamp) and run much, much cooler than the old tungsten things. A LED bulb of around 7 watts puts out as much light as a 100w incandescent bulb. The bluer daylight LED type are also more 'actinic' than the yellowish Photocresenta enlarger bulbs. Link to comment Share on other sites More sharing options...
JDMvW Posted February 19, 2021 Share Posted February 19, 2021 Which forum should I be asking this question in please? THanks It looks like you're doing OK here, but alternatives (perhaps not as much visited these days though) are Classic Film Cameras or Film & Processing. 1 Link to comment Share on other sites More sharing options...

glen_h Posted February 28, 2021 Share Posted February 28, 2021 Other voltages are not unusual if there is a regulator between the bulb and line. For black and white, most don't worry about it, but voltage also changes lamp color, so color enlargers like to have a regulator. -- glen Link to comment Share on other sites More sharing options...
rodeo_joe1 Posted March 1, 2021 Share Posted March 1, 2021 Other voltages are not unusual But 62 volts is! 12 or 24 volts is standard for dichroic-reflector lamps. With 110/120 and 220/240 v AC for mains-driven lamps. Anything else and you have to look long and hard to find it. A search for "62 volt bulb" was a Googlewhack -1. Zilch, nix, nada.

Actually I don't know about enlarger bulbs, but there are 82V projector lamps: https://www.amazon.com/EXR-Bulb-82v-300w-Lam/dp/B004HL93QU/ref=asc_df_B004HL93QU/ -- glen Link to comment Share on other sites More sharing options...
glen_h Posted March 1, 2021 Share Posted March 1, 2021 EVW seems to be an enlarger lamp at 82V, also, though maybe also used for projectors. -- glen Link to comment Share on other sites More sharing options...
PapaTango Posted March 2, 2021 Share Posted March 2, 2021 The planetarium I worked at in the 70s had one of these. It was a complete mess--and as soon as I could convince the Board to spend the money it was replaced with a Beseler 45MXT enlarger... "I See Things..."
